The "SEET HardSeven 1.5 Street" model from Haibike, released in 2020, is a versatile mountain bike characterised by its robust construction and a wide range of technical features. The frame is made from 6061 aluminium and is fitted with rim brakes (V-brakes), giving the bike a solid and durable structure. The maximum rider weight is 120 kg, making it suitable for a wide range of riders.
The bike’s braking system consists of XLC V-brakes, which, together with the Shimano EF41 brake levers, provide reliable braking performance. The gear system is provided by the Shimano Tourney TY300 with 21 speeds, operated via the Shimano Tourney EF41 Rapidfire shifters. The front derailleur is also a Shimano Tourney TY300, enabling precise and smooth gear changes.
The bike’s fork is an SR Suntour SF19 XCE28 with a steel spring and 100 mm of travel, providing sufficient damping on rough terrain. The steel steerer tube measures 1 1/8" and has a threading width of 8 x 100 mm. Lighting is provided by a Trelock LS232 front light with 20 lux at the front and a Herrmans H-Trace Mini LED rear light at the rear, ensuring good visibility in traffic.
Other features include non-slip plastic pedals, an FP-B908L bottom bracket with BSA threading, and a Shimano TY301 aluminium crankset with 24–42 teeth. The cassette is a Shimano HG200 with 12–32 teeth, and the drivetrain is powered by a KMC Z51 chain. The handlebars are MTB-110 with a width of 680 mm, complemented by S-WAVE grips and a Haibike Components The Stem stem with a bar bore of 31.8 mm and an angle of 6°.
The bike features XLC X-630 D-WALL hollow-chamber aluminium rims and Kenda K-922 tyres in size 54-584 with reflective strips. The front hub is a Shimano Nexus C3000 hub dynamo and the rear hub is a Shimano TY500, both with black spokes. The wheelset is 27.5 inches in size.
The saddle is a Haibike Components TheSaddle, mounted on an aluminium seatpost with a diameter of 31.6 mm. Polycarbonate mudguards are permanently fitted to keep out dirt and water. An adjustable Ursus Mooi kickstand completes the package and ensures the bike stands securely.
